Chris Pratt Revealed The Worst Gift He Ever Gave A Teacher

Hint: It was just a chunk of concrete.

In the lead-up to the highly anticipated "Guardians of the Galaxy Volume 2" some of the cast joined Jimmy Kimmel for a game he called "Guess the Guardian". In it, Kimmel told members of the cast a fact about one of their own, and they had to guess who the fact was about.

Chris Pratt, Kurt Russell, Zoe Saldana, Dave Bautista and Michael Rooker were put to the test to see how well they knew their co-stars, but no one could have guessed some of the truly incredible facts Kimmel had about them all.

"In high school," Kimmel began, "this guardian gave his teacher a chunk of concrete and told her it was a piece of the Belin Wall".

As the gang turned their whiteboards around, Chris Pratt's simply read, "wasn't me Frau Novak sorry".

"This was maybe my greatest teacher I've ever had," Pratt admitted, "because I'm still proficient in German. I had this weird compulsion to kick rocks, wherever I was going, I had to kick the rock all the way there and I was late so I pocketed the rock and she said 'Kristoff, warum bist du zu spät?' (Chris, why are you late?) and I told her the story."

"I said my cousin was in the Navy and that he was there for the fall of the wall and that he had given me this piece of concrete which was really a piece of sidewalk."

Kimmel asked if he had ever told his teacher the truth.

"I don't think I've ever told her the truth," Pratt admitted shamefully, "I need you to know, Frau Novak, that I'm forever in your debt to your wonderful teaching." Finishing up by apologising in flawless German, no less.

Pratt wasn't the only one who had some amazing truths revealed in the segment. Zoe Saldana, who plays Gamora, was apparently suspended from school for making stink bombs. "I was trying to get kids to like me!"

Speaking of trying to win someone's favour, one of the latest additions to the cast Kurt Russell, who plays Ego the Living Planet (don't ask), apparently used a brick to chop the tip of his finger off to win the heart of his neighbour!

"Guardians of the Galaxy" will open in cinemas April 25.
